what effect does liquid morphine have on a terminally ill lung cancer patient. My husband has a pleural effusion and multiple lesions on his metastatic lung. He is 62, 190lbs and started with colon cancer 8 years ago. 3 years ago the cancer he had an operation to remove a tumor from the right lobe and 30% of his lung. After 1 year after chemo, the cancer returned to the same area. He was given 6 months to live 10 mths ago. Now, discontinued chemo after 9 wks and no improvement. He s under Hospice care, has a cough and no energy. Just lays in bed most of the time and is on oxygen most of the day. The morphine and lorazepam doesnt seem to help much but does allow him to sleep some at night.
